Shadow World: Shadow World Quest-Seekers, Book, 1

Modern-day teenager Denzel suddenly finds himself in a world that looks like that of King Arthur's Court. His Bible has become a literal sword, and his faith a shield in his hand. According to the chief knight, he has been in this real world countless times and refers to the world Denzel came from as the shadow world. The knight explains that once someone remembers the shadow world, he will likely not forget it or the real world again. Both worlds affect each other.
